A motorcycle helmet includes a jaw protector pivotably attached to the helmet along opposite sides thereof. The jaw protector is provided with at least one releasable lock fixing the jaw protector in a lowered use position. The lock is deactivated for enabling a pivoting of the jaw protector to a raised position.

Jaw protecting apparatus of helmet

The present invention relates to a band buckle which is capable of fabricating a buckle based on a set formed of an upper ring and a lower ring, quickly releasing a bound force of an adjusting band by easily lifting only the upper ring when the adjusting band is inserted, and implementing an easier fabrication of a buckle and decreasing the fabrication cost of the same by forming a support portion in a rear end inner side surface of the lowering without forming the support portion in the upper ring. In the band buckle includes, the upper ring includes a handle protruded from both side surfaces of the front end potion of the same by more than the width, and the lower ring includes a support portion which is formed in such a manner that an extended portion is formed in an inner side of the through hole of the inner end portion and is bent upwardly in the band buckle which includes an upper ring and a lower ring each having a through hole and a fixing stripe which binds the rear ends of the upper ring and the lower ring.
